introduction | ammonium thioglycolate is a chemical used to straighten hair. Compared with other products, this chemical causes less damage to the scalp and hair and does not taste too heavy. Its function is to make the hair follicles more permeable and break down the disulfide bonds that curl the hair. This product is used as the first step in the thermionic straightening system. |
mechanism of action | removal of ammonium mercaptoacetate requires thorough rinsing. After the hair is styled and straightened, the next step is to apply a hydrogen peroxide solution. Hydrogen peroxide solution can produce new bonds in new hairstyles. Generally speaking, the fewer bonds are formed, the less curled hair. If this process is repeated excessively, the hair will become fragile and break easily. |
application | ammonium thioglycolate is mainly used as perm agent in cosmetics and skin care products. the risk coefficient is 4, which is relatively safe and can be used safely. cosmetic skin care products containing ammonium thioglycolate should be used with caution for pregnant women. ammonium thioglycolate has no acne-causing property. |
use | reagents for determination of iron and pharmaceutical industry are used as hair rolling agents and nutrient solutions in cosmetics to play a shaping role used as hair rolling agents and nutrient solutions in cosmetics to play a shaping role; It can also be used as PVC stabilizer, etc. |
